Celltex Therapeutics Corp.

Celltex Therapeutics Corp. has attracted attention since it was revealed Dr. Stanley Jones treated Perry with his own stem cells during back surgery in July 2011 and in follow-up appointments. Before their reinjection, Perry’s stem cells were stored and grown at Celltex.

The U.S. Food and Drug Administration has received a complaint alleging the Houston company involved in Gov. Rick Perry’s unregulated adult stem-cell operation is a potential danger to patients and not in compliance with federal law.

In an eight-page letter sent last month, University of Minnesota bioethicist Leigh Turner called on the FDA to investigate Celltex Therapeutics Corp., which banks people’s stem cells for future reinjection in the event of disease or injury. Perry was the company’s first customer last year.
